geo-rep / gsyncd: use RTLD_GLOBAL while loading libgfchangelog

Browse Source 
With the RPC based changes to {libgf}changelog, loading shared
objects dynamically would need symbols to be available from
other shared libraries. As an example, creating an RPC listner
loads the RPC transport shared object which requires symbols
to be available from already loaded shared objects.

Using RTLD_GLOBAL makes the symbols available for symbol
resolution of subsequently loaded libraries.
